Key Points

Evaluate how different irrigation solutions influence the microhardness and surface roughness of Biodentine used for root perforation repair.
76 Biodentine discs (5 mm × 2 mm) were fabricated under standardized conditions.
Discs were randomly assigned to four groups: distilled water, 2.5% sodium hypochlorite, 9% etidronic acid, and mixed HEBP/NaOCl, with 5 min exposure.
Surface roughness and microhardness were measured post incubation at 37 °C for 24 hours.
The HEBP/NaOCl group showed significantly lower microhardness compared to all other groups (p<0.05).
Surface roughness was highest in groups treated with HEBP and HEBP/NaOCl compared to distilled water and NaOCl.
